Texas Instruments CC3200 WiFi SensorTag is Now Available for $40

Texas Instruments launched SensorTag in 2013, and at the time there was just a Bluetooth 4.0 LE version with 6 different sensors. I bought one for $25 at the time, and tried it with a Raspberry Pi board and a BLE USB dongle. Since then, the company has launched a new multi standard model (CC2650STK) supporting Buetooth low energy, 6LoWPAN, and ZigBee, and has just started to take orders for CC3200 WiFi SensorTag for $39.99, which seems expensive in a world of $2 ESP8266 modules. But let’s see what the kit has to offer: Wireless MCU – Texas Instruments CC3200 SimpleLink ARM Cortex-M4 MCU @ up to 80 MHz, with up to 256KB RAM, Hardware Crypto Engine, DMA engine Storage – 1 MB serial flash memory Connectivity – 802.11 b/g/n WiFi with on-board inverted-F antenna with RF connector for conducted testing Sensors – Gyroscope, accelerometer, compass, light sensor (OPT3001), humidity […]

Omron Project Zero 2.0 is a Thinner Wrist Blood Pressure Monitor & Smartwatch

Omron Project Zero BP6000 blood pressure monitor & smartwatch / fitness tracker was unveiled at CES 2016. The device was due to be released at the end of 2016 pending FDA approval, but the launch has now been delayed to spring 2017, and it will be sold under the name “HEARTVUE”. The company has however showcased a new version at CES 2017, for now just called Omron Project Zero 2.0 that has the same functions but is more compact and lightweight. The watch will also work with Omron Connect US mobile app, and can record accurate blood pressure, as well as the usual data you’d get from fitness trackers including activity (e.g. steps) and sleep, as well as smartphone notifications. Blood pressure measurement can be activated by the user by pressing a button and raising his/her wrist to the height of the chest. The goal is the same as the […]

You Can Buy AirPods-like Wireless Bluetooth Stereo Earbuds for $16 and Up

Most Bluetooth headsets on the market actually come with some sort of wire or holding mechanism, which may not always be convenient, for example I can’t use mine comfortably while lying down on the bed. But that to electronics miniaturization, companies have recently started to offer truly wireless Bluetooth earbuds, including Apple’s yet-to-be available $159 Airpods. This morning I noticed two similar products in new arrivals list, first with $59.99 QCY Q29 mini Earburds on GeekBuying, and then even cheaper, but not quite as good looking (and likely not so good sounding), “FreeStereo Twins Wireless Bluetooth v4.1 In-Ear Headset w/ Mic” on DealExtreme going for just $22.25 including shipping. Let’s start with QCY Q29 earbuds specifications: Connectivity – Bluetooth 4.1 with HFP, HSP, A2DP, AVRC protocols support; up to 5-10 meter range Built-in Microphone Charging port – pogo on earbuds, micro USB to storage/charging box Battery – 45mAh for up […]
